IMPROVEMENT IN BLANKS FOR WATCH AND CLOCK DIALS.

Specification forming part of Letters Patent No. 216,917, dated June 2-1, 1879; application filed November 1, 1878.

To all whom. it may concern:

Be it known that I, WILLIAM A. ALES, of Auburndale, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Blanks for atch and Clock Dials, and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing, forming a part of this specification, in which the figure represents a vertical central section of a blank embodying my invention, which I will first proceed to describe, and subsequently to point out in the claims its novel characteristics.

The object of this invention is to produce a blank from a single piece of material that includes means for attaching the same to the movement and for supporting the dial proper and protecting the edges thereof, and whereby a firm and durable blank having the described features may be produced in a single opera tion.

In the drawing, a represents the depressed face or seat upon which the dial is arranged, the surroundin raised edge or bead 0 serving to maintain the dial in proper position and form a guard for the protection of its edge. The central perforation, c, is also formed so that a vertical flange surrounds the same to serve a like purpose. (1 represents a circumferential flange depending from the opposite side of the blank, and is intended to embrace the edge of the wateh-plate and be firmly held thereto by its natural elasticity or in any other suitable manner.

This blank is produced from a sheet of copper or other analogous substance by means of a die capable of cutting the same in circular shape, compressing it to the form shown, and punching the central perforation in a single operation, which will be readily understood by sheet-metal workers.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is V 1. A blank for watch or clock dials made in one piece, and having the bead I) at its periphcry and the flange around its central perforation, 0, for protecting both theinner and outer edges of the dial, substantially as described and shown.

2. The blank for watch or clock dials described, having face a, bead b, flanged perfo ration c, and circumferential flange (I, made in one piece of sheet metal, constructed and arranged substantially as set lorth and shown.

WILLIAM A. WALES.
